Abstract
Description
- The present invention relates to the field of snow sports, such as downhill skiing or snowboarding. More precisely, it relates to a snow gliding board, and to a set of at least two such snow gliding boards.
- Conventionally, a snow gliding board has an internal structure which defines its mechanical behavior and which comprises a longitudinal core and one or more reinforcements, for example a lower reinforcement and an upper reinforcement disposed on either side of this core. The internal structure of the gliding board is protected by a covering. In particular, its bottom and its top are lined respectively with a sliding base and an upper protective layer, which is visible and generally decorative.
- Conventionally, this upper protective layer consists of an outer skin or film, which is made from a single material or has the form of a multimaterial complex. In general, the upper reinforcement of the internal structure extends against this outer skin, the shape of which determines its own.
- In this respect, the outer appearance of the top of the gliding board and, in particular, its shape, are often selected according to aesthetic considerations. This shape of the top of the gliding board determines that of the outer skin of the upper protective layer. Usually, as described above, the shape of this outer skin in turn determines that of the upper reinforcement.
- In short, in most present-day gliding boards, the final shape of the upper reinforcement often results from non-technical considerations, whereas it influences the mechanical properties defined by this upper reinforcement.
- In other words, the consideration of aesthetic factors affecting the shape of the top of a snow gliding board generally constitutes an additional technical constraint, which must be taken into account when designing the snow gliding board. In particular, once the shape of the snow gliding board is modified for aesthetic reasons, a new analysis of the internal structure of this board must usually be carried out and usually leads to a new definition of this internal structure.
- Any technical study, any new development and any new fabrication incurs costs, including those associated with the reference listing and storage of different elements, albeit intended to perform similar functions in several ranges of gliding boards.
- To avoid such costs, it is known to place a sort of pad, inert or not, between the upper reinforcement and the skin of the upper protective layer. However, the hot shaping of this skin in a mold, during the fabrication of the gliding board, may be accompanied by appearance defects, such as deformations, cracks and/or shifts of the printed motifs, above the pad, insofar as this pad has a significant size.
- Document FR-2 873 591 proposes to make a cutout in the upper protective layer of a snow gliding board and to place therein an insert defining a gripping zone of the gliding board. The insert material may be a rubber. In fact, it is selected to facilitate the gripping of the gliding board. For the same purpose, this gliding board has undulations for inserting the fingers of a hand, at the insert, which has a constant thickness, substantially equal to that of the upper protective layer.
- Document FR-2 823 126 describes a method for fabricating a snow gliding board of which an upper protective layer comprises an insert. This insert has substantially the same thickness as the upper protective layer, to avoid projecting beyond it once accommodated in a cutout made in this upper protective layer.
- In document EP-0 774 280, a window cut out in an upper protective layer of a ski is closed by an added plastic part. Beyond the edge of the window, this plastic part passes below the upper protective layer and forms a pad in relief toward the interior of the ski.
- Document FR-2 540 391 describes a downhill ski board of which the top is defined in particular by a protective skin perforated with two cutouts. At each of these two cutouts, a sandwich structure is placed, comprising a reinforcement in particular, and which has the essential function of significantly affecting the mechanical behavior of the gliding board. The reinforcement of this sandwich structure extends against an outer protective skin whereof it follows the profile. In this way, a modification of the shape of the top of the gliding board at the abovementioned cutouts is reflected by a modification of the mechanical behavior of this gliding board if it is not offset by a new design of the elements defining the mechanical behavior of the gliding board. Here also, a modification of the shape of the top of the ski board for simply aesthetic reasons cannot be made easily without incurring substantial costs.
- Furthermore, each sandwich structure added to the board described in FR-2 540 391 is such that its fabrication mode is similar to that of a complete snow gliding board and therefore has the same drawbacks, particularly in terms of complexity and limited possible shapes.
- It is at least one object of the invention to facilitate a modification of the outer appearance of the top of a gliding board and, more precisely, of the shape of such a top.
- According to the invention, this object is achieved thanks to a snow gliding board comprising at least edges and a base of a lower assembly, an internal mechanical structuring beam and an upper protective layer, which partially covers said internal beam without significantly influencing the mechanical behavior defined by this internal beam, and which comprises a visible skin perforated with a cutout. The upper protective layer comprises at least one 3D visible decorative element which projects above said skin, while being fixed in said cutout so as to close this cutout and to be flush with the underside of said skin, at least this skin and the 3D decorative element together defining a 3D visible top of the gliding board.
- The shape of the top of the gliding board defined above may be easily modified, without changing the definition of the internal beam and therefore without any significant change in the behavior of the gliding board, particularly by replacing at least the 3D decorative element of the upper protective layer by another of different shape.
- Advantageously, an upper face of the internal mechanical structuring beam comprises a portion which has a predefined shape and above which said cutout is located, the 3D decorative element comprising a lower face substantially matching said predefined shape. Advantageously, this predefined shape comprises a cross section that is substantially straight. It may furthermore comprise a longitudinal section that is also substantially straight, in order to be substantially planar.
- Advantageously, the mechanical structure beam comprises at least one core, and an upper reinforcement which, at least directly under the 3D decorative element, extends substantially according to said predefined shape. As to this 3D decorative element, it may have a maximum thickness that is at least equal to three times the thickness of said skin.
- Advantageously, the 3D decorative element defines a hollow recess for accommodating an added part. For example, the latter may be a decorative mask fixed permanently or interchangeable, of which the visual appearance may recall that of the skin and/or may personalize the gliding board.
- Advantageously, the 3D decorative element forms means for retaining an added part. Such retaining means may comprise a back draft which is located at an overhang intended to extend above a nesting tab or an equivalent portion of the added part.
- Advantageously, the snow gliding board carries one accessory at least a portion of which is enveloped by the 3D decorative element. In this way, a connection can be provided participating in a harmonious integration of this accessory on the gliding board.
- Advantageously, the 3D decorative element is over-molded on at least a portion of said accessory, which may in particular comprise a plate for supporting a binding for a boot, such as a ski boot or a snowboard boot.
- The cutout may have a contour closed on itself, matching a contour of the decorative element. This cutout may also extend along the whole width of the gliding board and have an open contour, matching a contour of the decorative element. The decorative element is substantially adjusted without any clearance in the cutout so that its underside may be flush with the underside of the skin constituting the upper protective layer, that is, be located substantially at the same depth as the underside of the skin so as to prolong it, without extra thickness or other discontinuity.
- Advantageously, the 3D decorative element is an injection molded part. Such a part has a low production cost, while possibly having complex shapes. For example, being injection molded, the decorative element may have back drafts and/or threads obtained during the molding and not by a subsequent machining. It may also benefit from other possibilities offered by the injection molding technique. For example, the molded decorative element may be over-molded on an accessory of the gliding board or may be applied by a printing process routinely referred as “in-mold printing”.
- Advantageously, the 3D decorative element is a one-piece part made from a single material. It may also be a one-piece part made from a plurality of materials joined together via at least one interface.
- Insofar as the reinforcements of the ski board all form part of the internal beam, the 3D decorative element has no reinforcement.
- The invention also relates to a set of at least two gliding boards each as described above, which substantially comprise the same internal mechanical structuring beam and which are distinguished from one another in that the 3D decorative element of one of the gliding boards and the 3D decorative element of the other gliding board confer different shapes on the respective visible tops of these two gliding boards.
- The invention will be understood from a reading of the description as follows, provided exclusively as an example and in conjunction with the appended drawings, in which:
-
FIG. 1 is a perspective view of a ski board according to the invention; -
FIG. 2 is an exploded perspective view of an upper subassembly comprised by the ski board inFIG. 1 and which defines the top of this ski board; -
FIG. 3 is a perspective view of one of the elements shown inFIG. 2 ; -
FIG. 4 is a schematic cross section along plane IV inFIG. 1 , and shows the same ski board as thisFIG. 1 , but not in an exploded view; -
FIG. 5 is a view similar toFIG. 1 and shows a ski board according to an alternative embodiment of the invention; and -
FIG. 6 is a perspective cross section view along plane VI inFIG. 5 and partially shows the same ski board asFIG. 5 , but at a larger scale. -
FIG. 1 shows adownhill ski board 1 surmounted by aplate 2, for accommodating a binding for a ski boot. Thisski board 1 comprises a bottom, sides 3 and a top orupper face 4 defined by an upperprotective layer 5 that may be decorative. - As shown in
FIG. 2 , the upperprotective layer 5 comprises a plurality of assembled visible elements, including one 3Ddecorative element 6 and a skin orfilm 7 produced conventionally from a thermoplastic polymer. This polymer may be transparent or translucent, particularly if the underside of theskin 7 receives one or more coats of ink or varnish by printing or by any other appropriate means. - The
skin 7 is perforated with a cutout or through opening 8, which extends along the whole width of the glidingboard 1 and of which thecontour 9 matches aperipheral contour 10 of thedecorative element 6. Although it is open in the example shown, thecontour 9 may also be closed. -
FIG. 2 also shows two upper 11 and 12 accessories which, inFIG. 1 , are carried by thedecorative element 6 so as to be visible. - The
accessory 11 is more precisely an added decorative plate, of which the motifs and/or inscriptions can be selected in order to form a harmonious combination with a décor carried by theskin 7 and/or comprise technical data and/or references and/or advertising. The accessory 11 may also be a trompe-l'œil such as a hologram reproducing the interior of a ski board. It may also be a technical element, for example a vibration damping element. - The accessory 12 also has a decorative function. In fact, it is an added connecting piece, which is also involved in the fastening of the
decorative plate 11 in a manner described in detail below. - The
decorative element 6 is a one-piece flexible part, which is injection molded from a single polymer or a plurality of polymers to be joined together via one or more common interfaces. Its underside is substantially planar, and has a substantially straight cross section. On the other hand, theupper face 13 of thedecorative element 6 is in relief. Thisdecorative element 6 therefore has a variable thickness between its lower and upper faces, which have different shapes. - As can be observed in
FIG. 3 , theupper face 13 of thedecorative element 6 bounds ahollow recess 14 for accommodating thedecorative plate 11. Thepart 6 also bounds two lockingholes 15 which are part of the means for assembling the connectingpart 12 and which are disposed symmetrically to one another with regard to the plane of symmetry P extending along the length of theski board 1. Each lockinghole 15 is provided for the insertion of a tab for assembling the connectingpart 12 and terminates in an edge of thehollow recess 14 in order to be bordered upward by an overhanging portion which is intended to retain this assembly tab,reference 16 inFIG. 2 , and which has a back draft for this purpose. - The
decorative plate 11 is fixed to the bottom of thehollow recess 14, for example by adhesive. Its rear portion is also retained between thedecorative element 6 and the connectingpart 12, which is secured in place by the insertion of theassembly tabs 16 in theholes 15 and also ribs referenced 17 inFIG. 2 . Theribs 17 are intended to be trapped under theplate 2, which is the case inFIG. 1 . - As may be observed in this
FIG. 1 , thedecorative element 6 and the connectingpart 12 envelope the front portion of one edge of theplate 2, in order to protect the front of thisplate 2 and to make a harmonious connection between theskin 7 and saidplate 2 for an aesthetic integration of thisplate 2. Thedecorative element 6 may also serve for the harmonious integration of a part other than theplate 2. - The upper
protective layer 5 forms part of the outer envelope of which an example is proposed inFIG. 4 and which surrounds and protects an internal structure of theski board 1. In the example inFIG. 4 , this outer envelope comprises two edges or left and rightlongitudinal walls 18. It also comprises abottom sliding base 19 and two left andright edges 20, which border thisbase 19 and of which each is surmounted by one of thelongitudinal walls 18. - Inside the above envelope is an internal beam 21, that is a structure element in that it defines at least essentially the mechanical behavior of the
ski board 1 and which, for this purpose, comprises one or more reinforcements. In the example inFIG. 4 , the reinforcements of the internal beam 21 are two in number. They include a lower reinforcement 22 and an upper reinforcement 23, each of which has a substantially straight cross section. Each of the reinforcements 22 and 23 of the internal beam 21 comprises a hardened matrix and a structure of interlaced reinforcing fibers in this hardened matrix, which may in particular be a polymerized resin. Each of the reinforcements 22 and 23 extends to a level lower than theskin 7, while remaining below the cutout 8. - The internal beam 21 also comprises a core 24 which fills a space separating the reinforcements 23 and 23 from one another and which can in particular be made from expanded polyurethane foam or even from wood or from any other appropriate material.
- The
ski board 1 may be produced in various ways, for example by using one of the conventional methods for fabricating a snow gliding board in a mold, by hot molding. For example, when thisboard 1 is of the type with an injected core, the foam of itscore 24 is expanded between the reinforcements 22 and 23 and, in doing so, applies the lower reinforcement 22 against thebase 19 and the upper reinforcement 23 against the upperprotective layer 5 and against a leaktight film 25, which extends at least on either side of the junction line between thedecorative element 6 and theskin 7, in order to prevent any leakage of resin or polyurethane foam. In this way, the upper reinforcement 23 and theupper face 26 of the internal beam 21 have a predefined shape, which is substantially complementary to that of theunderside 27 of the upperprotective layer 5 and of which the cross section is substantially straight. - The
board 1 may also have a sandwich structure without injected core, in which case the application of its various components against one another results from their clamping between the lower and upper parts of the mold, during the closure of this mold. - Regardless of the method employed, the mold in which the
board 1 is fabricated can be simplified by the incorporation of thedecorative element 6. More precisely, its cavity comprises a recess which is designed to receive the emergent part of thedecorative element 6 and which may have a much simpler shape than thisdecorative element 6 insofar as the latter already has a definitive shape resulting for example from its injection molding. - In this respect, the
decorative element 6 has two perforatedpositioning wings 6A. When it is placed in the mold, it is handled by itswings 6A, thereby facilitating its accurate positioning, and which are dissociated from theboard 1 after the molding. - As may be observed in
FIG. 4 , thedecorative element 6 closes the cutout 8, where it is fixed in order to form a projection above theskin 7. Thanks to thisdecorative element 6, thetop 4 of theski board 1 may have a 3D shape, with one or more projecting reliefs and/or one or more hollows, and have a non-straight cross section, even when the upper reinforcement 23 has a straight cross section. In other words, the top 4 and the upper reinforcement 23 may have different cross sections and, more generally, different shapes. - The shape of the
upper face 26 of the internal beam 21 and that of the upper reinforcement 23 may be selected according to essentially technical considerations related to the desired mechanical behavior of theski board 1, taking little or no account of the shape selected for the top 4 of thisboard 1. The shape of this top 4 is mainly determined by thedecorative element 6 of theupper layer 5 which has the main function of protecting the internal beam 21 without significantly influencing the mechanical behavior of theski board 1. - It is easy to change the shape of the
top 4 of theski board 1 without necessarily modifying the mechanical behavior of thisboard 1. For this purpose, the upperprotective layer 5 is replaced by another having a decorative element similar to the one referenced 6 without having the same shape and/or without being located at the same place. The upperprotective layer 5 may also be replaced by another having a plurality of decorative elements similar to the one referenced 6. - One way to benefit from the system discussed in the above paragraph is to design two or more ranges of
boards 1 at low cost and to produce these two ranges, whereof theboards 1 substantially comprise the same internal beam 21 but not the same upperprotective layer 5, so as to be distinguished from one another by different shapes of theirrespective tops 4. Theboards 1 of one of the two ranges and theboards 1 of the other range substantially have the same behavior on snow, while having very different appearances. Increasing the number of ranges ofboards 1 by proceeding in this way has the advantage of only generating a slight extra cost. - Among the methods that can be used to insert the
decorative element 6 in the cutout 8 are those described in documents EP-0 972 544, FR-2 823 126 and EP-1 479 416. -
FIGS. 5 and 6 show aski board 101 in an alternative embodiment of the invention. In the following discussion, only what distinguishes it from theski board 1 is described. Furthermore, a reference used below to denote a portion of thisboard 101 similar or equivalent to a part referenced in theboard 1 is constructed by adding 100 to the reference identifying this part in theboard 1. - As may be observed in
FIG. 5 , theplate 102 is in two parts, which are arail 102A and arail 102B disposed in the prolongation of one another and whereof each is intended to accommodate a binding subassembly, such as a back heelpiece or a front toe piece not shown for the sake of clarity. - At the same time, the upper
protective layer 105 comprises two 3Ddecorative elements 106, each of which is housed without clearance in one of the twocutouts 108 arranged in the skin 107 of this upperprotective layer 105. Eachdecorative element 106 carries and retains one of therails - As may be observed in
FIG. 6 , one of thedecorative elements 106 is over-molded on the bottom portion of therail 102A, in order to imprison the assembly base, including two side andopposite wings 30 which form part of this base. Similarly, the otherdecorative element 106 is over-molded on therail 102B. - The
ski board 101 comprises aninternal beam 121 which is identical or substantially identical to the beam 21 and which is protected by an outer envelope comprising a plurality of elements connected in a sealed manner, including the upperprotective layer 105, thebase 119 and the two left andright edges 118. - Whereas its
internal beam 121 is identical or substantially identical to the internal beam 21 of theboard 1, theski board 101 has a top 104 of which the appearance and, in particular, the shape differ from thetop 4 of thisboard 1. - In the example shown, none of the
decorative elements 106 carries an accessory similar to thedecorative plate 11, or the connectingpart 12. But this is not mandatory. - The invention is not limited to the embodiments described above. In particular, it is not limited to downhill ski boards. On the contrary, a snowboard or a crosscountry ski board or even any other type of snow gliding board may also conform to the invention.
